2 Claims.

This invention was devised to correct or obviate certain objectionablefeatures of sanitary napkins of the single use or easily disposable typeand otherwise to improve the same.

As ordinarily constructed such articles include a core or filling ofcellulosic or other absorbent and disintegratable material in the formof a pad of superimposed sheets the edges of which are rough-cut orjagged and consequently tend to irritationand other sources ofdiscomfort not obviated and not alleviated by the usual gauze Wrappingwhich of itself is hard and abrasive to the touch.

Hence, the problem is to correct the condition stated and to insuregreater eciency and a greater degree of comfort without appreciablyadding to the cost of the article.

The nature, characteristic features and scope of the invention morereadily will be understood from the following detailed description takenin connection with the accompanying drawings,

2 is a transverse section of the pad and' facing elements in flat state,the gauze wrapper being omitted.

Fig. 3 is a transverse section of the complete article bent to U-form,showing how thefacing elements overlie the rough marginal edges or wallsof the pad.

Fig. 4 is a plan view of one of the facing elements.

Figs. 5 and 6 are details showing varied forms of facing elements.

In the drawings, 5 represents a standard or other suitable core orfilling formed or constructed of readily disposable material, and 6represents the usual gauze wrapper folded longitudinally to enclose thepad and to provide the usual tabs 7.

According to my invention there is provided above and below the pad andbetween the same and the gauze, facing elements, as at 8 and 9,consisting of a layer or bat of soft. conformable,

absorbent material such as by preference absorbt ent cotton. It will beunderstood that the facing elements 8 and 9 are disposed forindependence with respect to the pad in order to promote the maximumdegree of softness and conformability and so ascompletely to invest orcover the rough, irregular. ragged and crudely `assembled ornonregistering edges, which in the absence of cushionirm elements wouldmake for irritation and (Cl. 12S-290) other sources of extremediscomfort. In the further advancement of my inventive thought, the softpads or facing elements are provided with marginal extensions or wings10 which may be of the square outline, Fig. 4, or which may be of thegeneral arch form as indicated at 1l in Fig. 6.

The merit and significance of the soft pads or facings is graphicallyshown in the bent U-forrn, Fig. 3, wherein those elements not only aredisclosed as covering the larger areas of the filling thereby softeningthe gauze wrapper to an appreciable extent, but are shown as providing,through their overlap, a double cushion for the rough marginal walls ofthe filling. The construction has the further merit that it makes thearticle usable as to either side thereof. In short, there are no rightand wrong sides requiring the presence of some indicia properly 'todistinguish them.

What is claimed as new is:

1. A liner for sanitary napkins of the disposable type, comprising a batof soft brous absorbent material of substantially rectangular formhaving arcuate terminals inwardly of the side margins, whereby the sidemargins are defined as oifsettable wings, substantially as and for thepurpose described.

2. A sanitary napkin of the throw-away type,

-comprising a core or filling of the rounded end type, bats of softfibrous absorbent material of substantially rectangular form witharcuate ter- ROBERT W. JOHNSON.
